[Ethical problems in geriatrics from the family physician's viewpoint].

The picture of the 'youthful elderly' will develop further in a positive way because elderly people will not only experience a further increase of their average life-expectancy but also of their physical and psychic health and efficiency. Strict adhesion to calendar data means for the elderly that he is easily excluded from social performance and functionality of life. In order to meet the needs and expectations of the elder generation we need more overlapping linking of the different life periods, i.e. more sensitivity for individual arrangements. Increasing burden on the younger generation by increasing multimorbidity and needs for nursing may evoke responsibility for our patients. Therefore we practitioners should readily fulfill our duty to be in charge for the wellbeing of our aging patients. Social sensitivity for dignity in borderline situations depends on the acceptance of illness and needs for nursing as a natural part of our human existence.

[The early rehospitalization of elderly patients. Causes and prevention].

The causes of early rehospitalization (within 3 weeks) of very elderly patients, its possible avoidance and appropriate preventive measures were analysed retrospectively in patients of a geriatric hospital. Included were all those patients who had been admitted to the hospital from their home several (mean: five) times between 1987 and 1990 (48 women, 19 men; mean age 81.3 +/- 7.2 years--a total of 331 re-admissions). The most frequent diagnoses were heart failure (38.8%), acute cerebrovascular accident or its sequelae (31.3%), dementia (23.9%), fall or its sequelae (22.3%) and diabetes (20.9%). Of the 331 re-admissions 87 (26.3%) occurred during the first 3 weeks after discharge. The most important reasons of this early re-admissions were inadequate home care (41.4%), undesirable drug effects and non-compliance (25.3%), as well as rapid progression of the basic disease (14.9%). In the judgement of the hospital team more than 40% of the early re-admissions were avoidable, among those re-admitted because of inadequate home care and those in connection with drug intake even more than half. Early hospitalization is frequently avoidable, if individual geriatric assessment is undertaken and discharge carefully planned.

Patient compliance with drug treatment--new perspectives on an old problem.

Compared to other variables being considered in therapeutics, patient compliance has long been given minor attention although it affects every aspect of medical care. Limited methodology of compliance measurement, in particular, has hampered major progress in research, and pre-conceptions have been reiterated. However, there is a recent surge in interest derived from new data revealed by reliable methods, i.g. continuous medication (compliance) monitoring. The visualization of dynamics in drug regimen compliance over time offers unique opportunities, both to scientific drug evaluation and therapeutics in medical practice. New perspectives related to the descriptive and explanatory side of the problem are outlined by giving examples from various therapeutic fields.

[Therapy for smoking: consensus in German-speaking countries].

The german speaking countries (Austria, Germany, Switzerland) are not the most advanced in the world when it comes to the control of tobacco related diseases. The medical system in these countries has yet to be convinced that smoking cessation is not only necessary but feasible. In order to provide a basic document for further activities, a consensus development process was initiated. The consensus development process forms part of the activities performed by the UICC (International Union Against Cancer) Project Smoking Cessation, which is a project within the framework of the UICC Tobacco and Cancer Programme. The 1988 Report of the US Surgeon General states very clearly, that the use of tobacco products is not a matter of free choice, but is the result of an addiction as scientifically valid as the addiction to heroin and other narcotics. The scientific literature provides informations on many methods and techniques for a smoking cessation, both pharmacological and non-pharmacological. Many pharmacological approaches have been tried to treat nicotine dependence in man. According to scientific standards and many controlled studies, nicotine has been the only drug found to be effective in treating nicotine dependence. Many techniques, ranging from self help to sophisticated combined therapeutic approaches including pharmacological interventions, are now available to deal with the nicotine addiction. Smoking cessation treatment uses time, effort and other resources and the question of reimbursement for these services has to be considered. As with any other form of treatment, costs needed to be paid either by the individual patient/client and/or by other sources including private and national health insurance systems.(ABSTRACT TRUNCATED AT 250 WORDS)

Nutritional status of the very old: anthropometric and biochemical findings in apparently healthy women in old people's homes.

To obtain reference values for comparison with malnourished geriatric patients, the nutritional status of 50 apparently healthy women aged 75 or older living independently in two old people's homes in Heidelberg was examined. All women were able to walk, and were free from overt disease and signs of mental deterioration. Anthropometric measurements (body height and weight, triceps skinfold thickness, midarm circumference) and biochemical determinations of protein and vitamin status were performed. Anthropometric parameters were similar to those obtained in "younger" samples of healthy elderly, lower than those reported in younger adults, and markedly greater than those reported in geriatric patients. The majority of biochemical findings were within normal reference ranges established for healthy young adults. Only plasma retinol concentrations were below the reference limit in 8 women (16%). These findings show clearly that even in the very old, major alterations in biochemical indicators of nutritional status are rare. Neither advanced age nor institutionalization are associated with malnutrition. This obviously suggests that malnutrition in old age is mainly related to physical and mental disabilities.

Measurement of drug compliance by continuous electronic monitoring: a pilot study in elderly patients discharged from hospital.

OBJECTIVE: A pilot study to assess patient compliance with medication by using a new measurement technique, continuous electronic monitoring. DESIGN: Survey. Compliance monitors were provided to eligible patients at discharge from the hospital to measure drug intake behavior prospectively for a period of 3 weeks. SETTING: Ambulant patient care after discharge from a geriatric hospital, Krankenhaus Bethanien, which is affiliated with the University Clinic, Heidelberg. PATIENTS: A consecutive convenience sample of 18 independently living elderly patients (median age 76 years) completed the study. The patients were on maintenance therapy with cardiac glycosides and/or potassium-sparing diuretics prescribed to be taken once daily. INTERVENTION: The monitoring method provides information about patients' real timing of drug use by continuously recording date and time of openings and closings of the medication containers (monitors). In addition to a standard measure, the percentage of prescribed doses taken, information about regularity of drug use is obtained. RESULTS: Compliance, percentage of prescribed doses taken, was remarkably variable; it ranged from 24% to 100%, 95% CI: 62%-84%. Mean compliance declined from the first to the third week after discharge, 85% vs 69%, 95% CI: 74%-95% and 56%-81%, respectively (P < 0.05). Omissions of doses, the predominant pattern of non-compliance, were observed in 17 of 18 patients. Regularity of dose timing, as defined by the number of interdose intervals within 24 h +/- 15%, varied from 10% to 100%, 95% CI: 46%-76%. CONCLUSIONS: Continuous electronic monitoring revealed highly variable compliance in patients prescribed maintenance therapy. Even with a once-daily regimen, persistent and high compliance cannot be assumed. The monitoring technique may be of great value to research and, possibly, to practical therapeutic management.

Malnutrition in geriatric patients: diagnostic and prognostic significance of nutritional parameters.

Nutritional status was assessed in 300 geriatric patients aged 75 years or more using clinical, anthropometric, biochemical and immunologic methods. Relations between different assessment methods and their prognostic significance with regard to 18-month mortality were examined. For biochemical variables 10% (prealbumin, vitamin B6) to 37% (vitamins A and C) were below conventional limits. In 44% of the patients lymphocytes were diminished. 44% were anergic. Judgement of nutritional status by clinical impression resulted in 22% being deemed undernourished. Clinical diagnosis of undernutrition was associated with low anthropometric measurements (p less than 0.05 for all parameters) and a high prevalence of low biochemical values (p less than 0.05 for albumin, prealbumin, transferrin, vitamin A, vitamin B1). The mean values of all anthropometric variables, plasma proteins, vitamins A and C were significantly lower in patients who died within the following 18 months compared to survivors. The greatest prognostic significance was related to the clinical diagnosis of malnutrition. We conclude that clinical assessment is useful for the evaluation of nutritional status in geriatric patients and the best of numerous nutritional parameters to estimate risk of long-term mortality.

Dosage frequency and drug-compliance behaviour--a comparative study on compliance with a medication to be taken twice or four times daily.

The objective of the study was to investigate patient compliance with two different dosage regimens. Ethinyloestradiol 80 micrograms daily was prescribed to 35 female outpatients to be taken as 20 micrograms four times daily or 40 micrograms twice daily for 7 days. It was given to standardise cervical mucus before a sperm cervical mucus penetration-test (SCMPT) was performed. Sixty-five patients with primary infertility (mean age 29.9 y) completed the study. Compliance was assessed by microprocessor-based compliance monitoring. Besides compliance (percentage of prescribed doses taken), the adherence of the patients to the dosage schedule was evaluated--'regimen compliance'. The latter parameter of drug intake behaviour was calculated by the number of days in which 2 (BID) or 4 openings (QID) were recorded by the electronic monitor. As a third parameter, the deviation from the prescribed dosing intervals, i.e. 12 or 6 h, was also determined. Partial compliance was the predominant finding and only 9 patients (13.8%) were over-compliant. Mean compliance was 75.7% in all 65 patients as a group, range 7.1 to 143%. The mean compliance with the QID regimen was 67% compared to 85% with the BID regimen. 'Regimen compliance', the percentage of doses taken on schedule, was 36% and 63% for the QID and BID regimens, respectively. Drug-intake behaviour was more erratic with the QID than the BID regimen, as indicated by the 55% of opening intervals recorded which exceeded the range of 3-9 h (mean: 6 h), compared to only 19% exceeding 6-18 h intervals (mean: 12 h).(ABSTRACT TRUNCATED AT 250 WORDS)

Drug-prescribing patterns in old age. A study of the impact of hospitalization on drug prescriptions and follow-up survey in patients 75 years and older.

A prospective drug surveillance study was undertaken in 300 elderly patients admitted to a geriatric clinic. Prescribing patterns were determined on admission, at discharge and 3.6 and 18 months after discharge. Patients referred from long-term care institutions were on significantly more drugs than non-institutionalized subjects. A 34% reduction in the number of medicines prescribed at discharge was accompanied by a significant decrease in the mean number of prescriptions per patient, from 4.3 to 2.8, irrespective of whether the patient was institutionalized. Polypharmacy, defined by 5 or more concomitant drugs, declined from 43 to 17%. Dosage schedules were simplified in the majority of patients, as expressed by a significant decrease in the mean number of daily doses to be taken from 6.7 on admission to 4.4 at discharge. Cardiovascular drugs, diuretics and psychotropic drugs accounted for 64% of all drug prescriptions. At discharge, prescription frequencies were reduced for most medication categories, except diuretics and gastrointestinal drugs, which were being taken more often. The prescribing frequency of cardiac glycosides, the single most frequently prescribed drug class, decreased from 60 to 33% of the patients. Three months after discharge, prescribing patterns and frequencies were found to be very similar to the pre-admission situation. Eighteen months after discharge, overall drug use had increased by 15% compared to admission, and polypharmacy was recorded in 54% of patients. It is concluded that a substantial reduction in drug prescriptions was possible in the majority of elderly patients, particularly if they are institutionalized, on admission to a geriatric clinic.(ABSTRACT TRUNCATED AT 250 WORDS)

[Malnutrition in old age--results of the Bethany nutrition study].

One of the nutritional problems in elderly people is undernutrition, which is multifactorial in origin: The causes cannot only be seen in poor nutrition. Physical handicaps such as problems with chewing and swallowing, difficulties to cut food, immobility and mental restrictions are responsible for reduced food intake and malnutrition. Psychic and socio-economic problems such as depression, life events and loneliness may reduce appetite; poverty also contributes to the risk of undernutrition. As a result of our investigations of 300 geriatric patients, physical handicaps with influence on nutrient intake such as immobility or chewing problems were found in nearly 50% of all cases; undernutrition was observed in 22% of the patient group. In a group of 50 apparently healthy women aged 75 or older, the frequency of risk factors as well as the frequency of malnutrition was remarkably lower. These results confirm the thesis that, in most of the cases, undernutrition is related to medical problems and to the simultaneous presence of several of the above-mentioned risk factors. As a conclusion, treatment and prevention of malnutrition have to consider individually the elderly person's complete life situation. Present risk factors have to be removed, if possible; even better would be to avoid them.

Compliance with short-term high-dose ethinyl oestradiol in young patients with primary infertility. New insights from the use of electronic devices.

The objective of the study was to investigate patient compliance with ethinyl oestradiol therapy. Medication was prescribed to be taken in 20-micrograms doses four times daily for seven days. Oestrogens are prescribed for standardization of the cervical mucus before the sperm cervical-mucus penetration test (SCMPT) is performed. Relation of drug compliance with adverse drug reactions reported by the patients. The methodology used in this study was continual microprocessor-based monitoring by means of the Medication Event Monitoring System, MEMSTM. Adverse drug reactions were recorded by means of standardized interviews. Investigations were carried out on thirty female patients, mean age: 28.8 years (range 21 to 36 years), with primary infertility, mean duration of infertility: 3.9 years (range 9 months to 8 years). The results showed that individual patients' compliance was remarkably variable, ranging from 14.3% up to 136%. The average compliance was 65%. Less than 30% of the prescribed doses were taken on schedule. Administration of oestrogens was effective in all but one patient. High cervical indices were documented irrespectively of the dose taken. In answer to the questionnaire, 24 out of 30 women reported side effects, of which 79% were rated by the patients as being mild. The lower the drug compliance was, the more adverse reactions were reported. In patients who took more than 65% of the drug, this inverse relationship was statistically significant (r = -0.71, p = less than 0.01). Our conclusion is that the empirically fixed daily dose of 80 micrograms of ethinyl oestradiol for seven days appeared to be too high in regard of the observed dose response, i.e. cervical mucus quality. A dose finding study, including compliance monitoring, seems to be reasonable. Within further studies, a simpler dosage regimen should also be taken into account. The observed association between patients' reports of adverse effects and drug compliance deserves further investigation.

Dynamics of drug regimen compliance--its assessment by microprocessor-based monitoring.

The utility of a new microprocessor-based method for continuous monitoring of compliance in taking solid medicaments has been evaluated. Medication intake in 31 ambulant patients was assessed in a prospective observational study under the conditions of routine practice. The patients (aged 14-87 y, mean 50 y) were receiving long-term drug treatment for various chronic diseases. There was marked interindividual and intraindividual variation in compliance with different drugs. Deviations from the prescribed dosage regimens were caused by omission of doses (22.7% of prescribed doses) and intake of extra doses (5.6% of prescribed doses). Continuous monitoring revealed that in 19% of the monitoring period no medication was taken, in 13% there was partial intake, and in 8% extra doses were taken. Patient-initiated drug holidays occurred in 50% of patients. They were responsible for 76% of the medication-free time. It is concluded, that continuous compliance monitoring is practicable in ambulatory patients. It provides information about the dynamics of drug intake behaviour that cannot be obtained from medical histories or from clinical or laboratory examination. The information could be used effectively in individual patient care and in clinical drug trials.

[Does your patient take his medicine? Compliance problems in clinical practice].

There is convincing evidence from compliance research that deviations from the prescribed drug regimen is the rule rather than the exception. Demographic and psychosocial patient factors poorly correlate with non-compliance, whereas features of the disease, mechanisms of treatments, regimens and the patient physician interaction are particularly important determinants of patients' compliance behaviour. Non-compliance can not be predicted. There are problems in the assessment of non-compliance, more particularly of its clinical consequences. New microprocessor-based technology evaluated essential insight into patients' compliance behaviour and revealed different patterns of non-compliance. On one hand, the therapeutic outcome can be impaired by non-compliance, on the other hand, however, certain patterns of non-compliance appear to be appropriated from the patients' point of view. In medical practice it is important to consider non-compliance as essential impact on drug therapy and to promote the discussion of this issue with patients.

[Anxiety and its control].

Anxiety has many faces--including suppressed anxiety and "non-anxiety". Our present age is increasingly being referred to as the "age of anxiety", our society as an "anxious society", probably because we constantly feel threatened not only by physical, but also by psycho-social anxiety. If we are unable actively to combat or escape from a threat, or to cope with emotional reactions and stress, insecurity, anxiety and fear result. If this becomes extremely pronounced and appears irrational to the person affected, the term phobia is employed to describe a specific fear (fear of bridges, crowds, confined spaces, etc.). The more susceptible the person, the smaller are his chances of compensating. The increase in anxiety disorders and psychosomatic disturbances seen today, are an indication that we must learn not merely to combat anxiety, but also to accept it.
